REPORT FOR THE DISTILLATION OEQAIQBQNAGEOIISMATERIALS- Application filed March 31, 1920. Serial No. 370,219.

To all whom it may concern.

Be it known that I, WILLIAM WILD, a sub- ]ect of the King of Great Britain and Ireland, and resident of Beechwood, Newton Drive, Blackpool, in the county of Lancaster, England, have invented certain new and useful Improvements in Retorts for the Distillation of carbonaceous Materials, of which the following is a specification.

This invention relates to horizontal or inclined retorts for the distillation of coal and like carbonaceous materials, and has for its object to provide an improved arrangement of retort which shall have high efficiency and give high gas yields whetherworked according to the continuous or the intermittent method.

My invention comprises a retort having a vertical or approximately vertical externally heated extension or chamber at its delivery end into which the coke from the horizontal or inclined portion of the retort is discharged either continuously or inter mittently and in which the said coke is retained at a high temperature for a sufficient period to be utilized for the production of water gas (which passes through the retort) from steam injected into the said ex tension or chamber.

Referring to the five accompanying sheets of explanatory drawings Figure 1 is a sectional side elevation on the line AB of Figure 2, and Figure 2 an end elevation looking from right to left of Figure 1 illustrating a retort setting having my invention applied thereto.

Figure 3 is'a sectional end elevation onthe line CD of Figure 1. Y

Figures 4 and 5 are sectional side elevation taken through a retort and to one side thereof showing the heating arrangements.

Figures 6 and 7 are views corresponding to Figures 1 and 2 but showing modified arrangements of retorts.

The same reference letters in the different views indicate the same parts.

The retorts a are provided with a vertical coke chamber 6 at their delivery end, the said chamber being formed of refractory material and being externally heated as hereinafter described. Steam is passed through a suitable conduit 0 in each chamber wall where it becomes highly superheated) into the interior of the coke chamber at d where it is converted into water gas and travels to and through the horizontal retort a where it mixes with and serves to carry off the gases and vapours generated during the distillation process. The gas offtake is shown at 6, Figure 4. At the bottom of the vertical coke chamber, I provide a suitable coke discharge chute f with its valve or closure piece as f, Figure 1. An inter cepting closure piece 9 for the coke is shown at Figure 4.

If the horizontal retort a be charged and discharged intermittently, I arrange that firstly the coke from the vertical coke chamber b is withdrawn therefrom. The coke in the horizontal portion of the retort is then discharged into the vertical coke chamber, and finally the horizontal portion is recharged. I may arrange that a small portion of the coke is left at the delivery end of the horizontal portion of the retort to serve as a stop for the new charge.

hen working continuously, the coke from the vertical coke chamber 6 may be withdrawn either continuously or intermittently.

If desired, I may cause the wall of the retort to deflect the coke being discharged fromv the horizontal to the vertical portion of the retort so as to break the coke off into suitable pieces.

The retorts may be heated by the proclucts of combustion from combustion chambers h (Figures 4 and 5), the gases passing back and forth across the retorts and finally down the opposite sides of the coke chambers Z2. Suitable walls or divisions m which may have gaps therein serve to support the retorts and to equalize the heating effect of the gases upon the latter. The waste gases pass into the regenerator brickwork (as shown in Figure 5) where the heat is utilized for preheating in adjacent passages as 0 (Fig. 4) the secondary air required for combustion in the chambers h. The producer for the gas for the combustion chambers h is shown at j and the producer gas passages at is (Figure 4). The coke from the retorts n is utilized in the gas producer which heats the retort 9 setting. (Figures 4 and 5) indicates the coal inlet to a retort.

I do not limit myself to any shape or arrangement of the vertical coke chamber with its heating means, but may modify the same to suit requirements. I prefer to employ relatively narrow retorts as shown in 1*"igu'res'5 and 6. Y 1

Having now described my invention What I claim as new and desire to secure by 5 Letters Patent is A horizontal retort, a Vertical coke chamber at the delivery end of said retort, combustion chambers externally heating said retort and said Vertical coke chamber, a coal inlet and gas outlet at the end of the retort 10 ren'i'ote'from the coke-chamberya closure for the lower end of said coke chamber, and a conduit supplying superheated steam to the lower endofsaid coke chamber.

WILLIAM WILD.
